GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007

Copyright (C) 2007 Free Software Foundation, Inc.
Everyone is permitted to copy and distribute verbatim copies of this license document,
but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates the terms andconditions of version 3 of the GNU General Public License, supplemented by theadditional permissions listed below.

0.

Additional Definitions.

As used herein, "this License" refers to version 3 of the GNU Lesser General Public
License, and the "GNU GPL" refers to version 3 of the GNU General Public License.

"The Library" refers to a covered work governed by this License, other than an
Application or a Combined Work as defined below.

An "Application" is any work that makes use of an interface provided by the Library, butwhich is not otherwise based on the Library. Defining a subclass of a class defined by theLibrary is deemed a mode of using an interface provided by the Library.

A "Combined Work" is a work produced by combining or linking an Application with theLibrary. The particular version of the Library with which the Combined Work was made isalso called the "Linked Version".

The "Minimal Corresponding Source" for a Combined Work means the Corresponding
Source for the Combined Work, excluding any source code for portions of the CombinedWork that, considered in isolation, are based on the Application, and not on the Linked
Version.

The "Corresponding Application Code" for a Combined Work means the object codeand/or source code for the Application, including any data and utility programs needed forreproducing the Combined Work from the Application, but excluding the System Librariesof the Combined Work.

1.

Exception to Section 3 of the GNU GPL.

You may convey a covered work under sections 3 and 4 of this License without beingbound by section 3 of the GNU GPL.

2.

Conveying Modified Versions.

If you modify a copy of the Library, and, in your modifications, a facility refers to afunction or data to be supplied by an Application that uses the facility (other than as anargument passed when the facility is invoked), then you may convey a copy of themodified version:a)under this License, provided that you make a good faith effort to ensure that, inthe event an Application does not supply the function or data, the facility still
operates, and performs whatever part of its purpose remains meaningful, orb)

under the GNU GPL, with none of the additional permissions of this License
applicable to that copy.

3.

Object Code Incorporating Material from Library Header Files.

The object code form of an Application may incorporate material from a header file that ispart of the Library. You may convey such object code under terms of your choice,provided that, if the incorporated material is not limited to numerical parameters, data
structure layouts and accessors, or small macros, inline functions and templates (ten orfewer lines in length), you do both of the following:a)Give prominent notice with each copy of the object code that the Library is usedin it and that the Library and its use are covered by this License.

b)

Accompany the object code with a copy of the GNU GPL and this license
document.

4.

Combined Works.

You may convey a Combined Work under terms of your choice that, taken together,effectively do not restrict modification of the portions of the Library contained in theCombined Work and reverse engineering for debugging such modifications, if you also
do each of the following:a)Give prominent notice with each copy of the Combined Work that the Library isused in it and that the Library and its use are covered by this License.

b)

Accompany the Combined Work with a copy of the GNU GPL and this license
document.

c)

For a Combined Work that displays copyright notices during execution, include
the copyright notice for the Library among these notices, as well as a reference
directing the user to the copies of the GNU GPL and this license document.

d)

Do one of the following:0)

Convey the Minimal Corresponding Source under the terms of this License,
and the Corresponding Application Code in a form suitable for, and underterms that permit, the user to recombine or relink the Application with amodified version of the Linked Version to produce a modified Combined
Work, in the manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.

1)

Use a suitable shared library mechanism for linking with the Library. A
suitable mechanism is one that (a) uses at run time a copy of the Libraryalready present on the user's computer system, and (b) will operateproperly with a modified version of the Library that is interface-compatible
with the Linked Version.

e)Provide Installation Information, but only if you would otherwise be required toprovide such information under section 6 of the GNU GPL, and only to theextent that such information is necessary to install and execute a modified
version of the Combined Work produced by recombining or relinking theApplication with a modified version of the Linked Version. (If you use option 4d0,
the Installation Information must accompany the Minimal Corresponding Source
and Corresponding Application Code. If you use option 4d1, you must provide
the Installation Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)

5.

Combined Libraries.

You may place library facilities that are a work based on the Library side by side in asingle library together with other library facilities that are not Applications and are notcovered by this License, and convey such a combined library under terms of your choice,
if you do both of the following:a)Accompany the combined library with a copy of the same work based on theLibrary, uncombined with any other library facilities, conveyed under the termsof this License.

b)

Give prominent notice with the combined library that part of it is a work based on
the Library, and explaining where to find the accompanying uncombined form ofthe same work.

6.

Revised Versions of the GNU Lesser General Public License.

The Free Software Foundation may publish revised and/or new versions of the GNU
Lesser General Public License from time to time. Such new versions will be similar in
spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Library as you received it
specifies that a certain numbered version of the GNU Lesser General Public License "or
any later version" applies to it, you have the option of following the terms and conditions
either of that published version or of any later version published by the Free Software
Foundation. If the Library as you received it does not specify a version number of theGNU Lesser General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.

If the Library as you received it specifies that a proxy can decide whether future versionsof the GNU Lesser General Public License shall apply, that proxy's public statement of
acceptance of any version is permanent authorization for you to choose that version forthe Library.
